Martin: I did not say there were no alternatives on Windows, I said there were no worthy ones. I think the list I presented are examples of software which is just better on the Mac. There nay be apps that cover the same field on Windows but they are not nearly as good.
Not enough Mac users realise we truly have the best software. We have loads of wonderfully designed gems that are Mac only, and far ahead of anything on Windows.
